[ssml] BLASTCLUST at low % identity threshold

Below 20% identity I see no change in the blastclust results. I would like
to know how blastclust uses the % identity in its cluster calculation,
i.e. does it align 'properly' first with a substitution matrix and then
compute identity from the resulting alignment?

Why do the results stay the same from 20% downwards?
